Copper-nickel nanowires deemed perfect fit for printable electronics

Duke University chemists created a new set of flexible, electrically conductive nanowires from thin strands of copper atoms mixed with nickel. A new study shows that the nanowires conduct electricity even under conditions that break down the transfer of electrons in plain silver and copper nanowires. They are an excellent alternative to use in printed electronics. Such products include electronic paper, smart packaging and interactive clothing, said Benjamin Wiley, an assistant professor of chemistry at Duke. His team describes the new nanowires in a NanoLetters paper published online May 29. The new copper-nickel nanowires are the latest nanomaterial Wiley's lab has developed as a possible low-cost alternative to indium tin oxide, or ITO. This material is coated on glass to form the transparent conductive layer in the display screens of cell phones, e-readers and iPads.
